Resistance spot welding ke ts'ebetso ea mantlha e sebelisoang liindastering tse fapaneng bakeng sa ho kopanya tšepe hammoho. Ho fihlella li-welds tsa boleng bo holimo, taolo e nepahetseng holim'a mekhahlelo ea welding e bohlokoa. Karolo e 'ngoe ea bohlokoa ke nako ea pele ho khatello ea maikutlo, e phethang karolo ea bohlokoa ho netefatsa botšepehi ba weld. Sehloohong sena, re tla tšohla mokhoa oa ho lekanya nako ea pele ho khatello ea mochini oa tjheseletsa oa letheba.
Resistance spot welding e kenyelletsa ts'ebeliso ea motlakase ho theha mocheso oa lehae sebakeng sa tjheseletsa, ho lateloa ke ts'ebeliso ea khatello ea mochini ho kopanya likotoana tse peli tsa tšepe hammoho. Nako ea pele ho khatello ke nako eo ka eona li-electrode li sebelisang khatello ho li-workpieces pele ho sebelisoa hona joale oa welding. Nako ena ke ea bohlokoa kaha e lokisa lisebelisoa tsa ho cheselletsa ka ho li nolofatsa kapa ho li hloekisa.
Bohlokoa ba Nako ea Pele ho Khatello
Nako ea pele ho khatello e na le tšusumetso e kholo ho boleng le matla a weld. Haeba nako ea pele ho khatello e le khutšoanyane haholo, lisebelisoa li ka 'na tsa se ke tsa nolofatsoa ka ho lekaneng kapa tsa hloekisoa, e leng se etsang hore ho be le weld e fokolang e nang le ho kenella hampe. Ka lehlakoreng le leng, haeba nako ea pele ho khatello e telele haholo, e ka lebisa ho futhumala ho feteletseng le ho senyeha ha li-workpieces, ho baka ho sotha le ho senya botšepehi ba motsoako.
Mokhoa oa ho lekanya
Ho lekanya nako ea pele ho khatello ho kenyelletsa mokhoa o hlophisitsoeng oa ho netefatsa maemo a nepahetseng a ho cheselletsa. Mehato eo u ka e latelang ke ena:
- Tlhophiso ea Mochini: Qala ka ho theha mochini oa tjheseletsa oa sebaka sa ho hanyetsa ka matla a lakatsehang a eleketrode, hona joale, le litlhophiso tsa nako ea welding.
- Nako ea Pele ea Khatello ea Pele: Khetha nako ea pele ea khatello e ka har'a maemo a tloaelehileng a kopo ea hau. Sena se tla sebetsa e le qalo ea ho lekanya.
- Teko ea Welding: Etsa letoto la li-welds tsa liteko u sebelisa nako e khethiloeng pele ho khatello. Lekola boleng ba li-welds ho latela matla le ponahalo.
- Fetola Nako ea Pele ho Khatello: Haeba nako ea pele ea khatello ea pele e fella ka li-welds tse seng maemong a tloaelehileng, etsa liphetoho tse ntseng li eketseha ho nako ea pele ho khatello. Eketsa kapa fokotsa nako ka li-increments tse nyane (mohlala, milliseconds) 'me u tsoele pele ho etsa liteko tsa weld ho fihlela boleng bo lakatsehang bo fumaneha.
- Tlhokomelo le Litokomane: Nakong eohle ea ts'ebetso ea ho lekanya, hlokomela ka hloko boleng ba weld 'me u tlalehe litlhophiso tsa nako ea pele ho khatello bakeng sa tlhahlobo ka' ngoe. Litokomane tsena li tla u thusa ho boloka tlaleho ea liphetoho tse entsoeng le liphello tsa tsona tse lumellanang.
- Ntlafatso: Hang ha u se u khethile nako ea pele ho khatello e lulang e hlahisa li-welds tsa boleng bo phahameng, u atlehile ho lekanya mochine oa ho tjheselletsa sebaka sa ho hanyetsa bakeng sa kopo ea hau e khethehileng.
Ho lekanya nako ea pele ho khatello mochining oa ho tjheselletsa sebaka ke mohato oa bohlokoa ho netefatsa tlhahiso ea li-welds tsa boleng bo holimo. Ka ho lokisa ka mokhoa o hlophisehileng le ho lekola nako ea pele ho khatello, o ka ntlafatsa ts'ebetso ea welding bakeng sa lisebelisoa tsa hau tse ikhethileng le ts'ebeliso, e lebisang ho li-welds tse matla, tse tšepahalang haholoanyane. Tekanyetso e nepahetseng ha e ntlafatse boleng ba weld feela empa hape e fokotsa monyetla oa ho ba le mefokolo le ts'ebetso e ncha, e qetellang e ntlafatsa ts'ebetso le katleho ea lits'ebetso tsa hau tsa tjheseletsa.
